“…Coated electrodes are now extensively used in the electrochemical field because they have both the mechanical properties of the substrate and the electrochemical properties of the coating. As one of the more traditional coatings, lead dioxide (PbO 2 ) has attracted considerable attention due to its demonstrated advantages, including low electrical resistivity, low cost, ease of preparation, good chemical stability, and relatively large surface area [4][5][6][7]. Thus, lead dioxide has already been used in waste water treatment [8][9][10], ozone generation [11,12], lead-acid batteries [13][14][15], analytical sensors [16], and the metal electrowinning process [17].…”

In this study, β-PbO 2-Co 3 O 4 composite coatings were synthesized on a substrate using the electrodeposition method in an electrolyte containing Pb 2+ and Co 3 O 4 particles. The preparation process study shows that the β-PbO 2 bath containing Co 3 O 4 particles becomes more stable for an ultrasonic dispersion time within 30 min, with the stability beginning to decrease after the ultrasonic time exceeds 30 min. Co 3 O 4 particles in the β-PbO 2 bath are positively charged, with anions being adsorbed onto the particles. The nucleation behavior study shows that the electric field force plays a dominant role in the adsorption process for the Co 3 O 4 particles. The nucleation and growth of β-PbO 2 on the Co 3 O 4 particles started for the particles closer to the substrate. In addition, the thickness of the β-PbO 2 layer on the Co 3 O 4 particles was inversely proportional to the distance between the Co 3 O 4 particles and the substrate. Compared to the pure PbO 2 electrode, the oxygen evolution overpotentials for the β-PbO 2-Co 3 O 4 electrode are decreased significantly, which demonstrates an energy-saving effect.

In this study, β-PbO2-WC composite coatings were synthesized on a substrate using the electrodeposition method in an electrolyte containing Pb 2+ and WC particles. The preparation process study shows that the β-PbO2 bath containing WC particles becomes more stable for an ultrasonic dispersion time within 30 minutes. WC particles in the β-PbO2 bath are positively charged, with anions being adsorbed onto the particles. Compared to the β-PbO2 composite electrode, the oxygen evolution overpotentials for the β-PbO2-WC electrode are decreased, which demonstrates an energy-saving effect. The nucleation behavior study shows that the co-deposition of WC particles into the layer has little effect on the crystal growth of β-PbO2. The main process during the deposition time of 0~5 min were the nucleation of the β-PbO2 grains, the adsorption of WC particles, growth of β-PbO2 grains, and WC particles coated.
